Plant scattered, altogether not more than h a lf an inch in height. Stem naked
below, very slender. Leaves spreading, remote, not more than 6- 8, o f a
pale reddish colour, obovate, entire, cuspidate, margined, and of a most
delicate loosely reticulated structure, nerve rather stro n g ; in the upper
leaves extending about two-thirds of their length, in the lower ones vanishing
about the middle. The margin and the nerve are of a dark red
colour. Fruitstalk a quarter o f an inch in length. Capsule small, dark
brown, obovate, or somewhat pyriform, nodding; the lid convex-conical.
Teeth of the outer peristome yellow, as long as the inner peristome, which
has no (?) ciliary processes between the segments.
For introducing into this work a plant only observed in
England, I have deviated from my rule, hitherto strictly observed,

England, however, has been so assiduously explored, that when
a new plant, so high in the scale of vegetation as a Moss, is
